Well, the XS series is APC's bottom-feeder line, so an egg laid here wouldn't surprise me. It shouldn't have acted that way, but you do tend to get what you pay for. There's a reason the 800VA Smart-UPS costs $200 while the low-end models cost $50.

The concept is good. The realization is a product designed for a very specific application.

I suppose you could figure out a way to make it work and it might have a slight performance advantage, but the cost penalty for a consumer and the installation issues make it a non-starter as far as I can tell.

If you have used one of these, please post more about your specific experience. I have one downstairs for my FIOS installation, I will take a closer look at it tomorrow and post a more detailed report.
